Surgical trauma and prolonged extra-alveolar exposure of the donor tooth's root sheath are both complicating factors during tooth autotransplantation surgery. This case report describes a 12-year-old female patient who underwent surgical transplantation of a maxillary second premolar to a central incisor site. A three-dimensional printed analogue of the donor tooth was fabricated from a cone beam (CBCT) scan of the tooth in order to minimise the extra-oral (exposure) time and frequency of trial insertions of the donor tooth into the recipient socket...

This original case report describes the morphologic changes caused by a mandibular condylar osteochondroma (OC) on a female patient and its treatment. The changes were identified by comparing her final records from a previous orthodontic treatment, without the presence of OC, to records taken before a second treatment, with a developed OC. The diagnostics and treatment for the OC and its consequences were described and discussed in this paper. Treatment included orthodontics with a lingual appliance, low condylectomy on the affected side, high condylectomy on the contralateral side, bilateral disc repositioning and orthognathic surgery...

INTRODUCTION: Aim of this study was to assess the registration of orthodontic systematic reviews in PROSPERO. METHOD: Seven databases were searched for orthodontic systematic reviews published in 2012-2016. After duplicate study selection and data extraction, descriptive statistics, followed by chi-square/Fisher exact tests were calculated. Finally, bivariable/multivariable regression with relative risks (RR) and 95% confidence intervals (CIs) was used. RESULTS: A total of 182 orthodontic systematic reviews were identified, 37 (20...

BACKGROUND: The TheraMon® microsensor is the most recent device developed to measure the wear-time of removable appliances. The accuracy has not been validated intraorally. OBJECTIVES: To determine 1) if the TheraMon® microsensor accurately records time when fixed intraorally, and 2) the effect of the intraoral location on the recorded time. METHODS: A prospective pilot study, using a convenience sample, was carried out in a UK hospital orthodontic department...

Dental concrescence is a rare dental abnormality resulting in the joining of two teeth at the level of the cementum. This is the first reported case of the orthodontic management of a dental concrescence and the options for patient treatment are discussed. In this case, a compromised occlusal result was accepted with restorative masking of the affected teeth.

OBJECTIVES: The objective of this study was to evaluate the influence of long-term storage on latex and non-latex orthodontic elastics. MATERIALS AND METHODS: The sample consisted of 300 orthodontic elastics, 150 latex and 150 non-latex (American Orthodontics(®) *(AO) and Morelli(®)) of medium force and a standard size of 3/16'' divided into 20 groups, 10 for each manufacturer, with 15 specimens each. The groups (G1*-G10* and G1-G10) were made up based on the manufacturer, storage temperature (ambient and refrigerated), material, and ambient humidity (exposed and non-exposed)...

Occasionally, orthodontists will be challenged to treat malocclusions and skeletal disharmonies, which by their complexity one might think that the only treatment alternative is the surgical-orthodontic approach. A male patient, aged 17 years old, was diagnosed with a skeletal Class III malocclusion, anterior open bite and negative overjet. An unpleasant profile was the patient's 'chief complaint' showing interest in facial aesthetics improvement. Nevertheless, the patient and his parents strongly preferred a non-surgical treatment approach...

OBJECTIVES: To explore the accessibility, usability and relevance of the British Orthodontic Society (BOS) online information resource (OIR), Your Jaw Surgery. DESIGN: Qualitative, cross-sectional study. SETTING: 5 UK sites. PARTICIPANTS: Patients before, during and after treatment for non-cleft skeletal discrepancy. METHODS: Patients were identified at joint clinics and recruited after having time to view the OIR...

OBJECTIVE: To investigate the effect of using mobile applications active reminders to improve oral hygiene in comparison to verbal oral hygiene instructions. DESIGN: Two-arm parallel randomised controlled trial. SETTING: orthodontic clinics at two branches of a university hospitals of the college of dentistry of Riyadh Colleges of Dentistry and Pharmacy, Riyadh, Saudi Arabia. PARTICIPANTS: Forty-four 12-year-old and older subjects...

INTRODUCTION: Tooth movement during orthodontic treatment is possible because of mechanical force-induced inflammation and remodelling in the periodontal ligament. Variation in the inflammatory response might be anticipated with initial aligning archwires of different composition. Myloperoxidase (MPO) is an enzyme found in neutrophil granules that represents an important marker of inflammation. The aim of this study was to measure MPO enzyme activity during initial alignment with orthodontic arch wires of different alloy types...

OBJECTIVE: The present study used the optical surface laser scanning technique to compare the facial features of patients aged 8-18 years presenting with Class I and Class III incisor relationship in a case-control design. MATERIALS AND METHODS: Subjects with a Class III incisor relationship, aged 8-18 years, were age and gender matched with Class I control and underwent a 3-dimensional (3-D) optical surface scan of the facial soft tissues. RESULTS: Landmark analysis revealed Class III subjects displayed greater mean dimensions compared to the control group most notably between the ages of 8-10 and 17-18 years in both males and females, in respect of antero-posterior (P = 0...

OBJECTIVE: Changes in the size of the sella turcica are frequently related to pathologies and syndromes. The aim of this was to compare the sella turcica dimensions in patients with unilateral and bilateral cleft lip and palate and non-cleft subjects. METHODS: Cone beam computed tomography (CBCT) images of three groups consisted of 20 patients with unilateral cleft lip and palate; 20 patients with bilateral cleft lip and palate and a control group consisting of 20 non-cleft subjects were the research population in this pilot study...

OBJECTIVE: To assess the knowledge and attitudes of orthodontic trainees towards orthodontic therapists (OTs) in the UK. DESIGN: Cross-sectional survey. SETTING: UK-based orthodontic trainees. MATERIALS AND METHODS: An electronic survey was sent to all members of the Training Grades Group of the British Orthodontic Society assessing exposure to OTs and their knowledge regarding current supervision guidelines and scope of practice...
